Hiring a solar company in Auburn

Solar companies working in Auburn, California file the permit in two systems: the automated Symbium portal, which the City adopted under Senate Bill 379, and then the City's Civic Access system for the documents and City fees. Pioneer Community Energy supplies Auburn's generation and PG&E delivers it. Get at least three written bids built on your own Pioneer and PG&E bill and compare them on the checks below.

Start with your Auburn electricity bill

Auburn was one of the founding cities of Pioneer Community Energy in 2018, so most Auburn homes get generation from Pioneer and delivery from PG&E on one PG&E statement. The Energy Commission's map places the whole city in both service areas. Have each bidder model your actual Pioneer and PG&E enrollment rather than a PG&E-only account.

Auburn's Symbium permit, step by step

Senate Bill 379 requires most California cities to offer automated, instant plan review for residential solar. Auburn meets it with Symbium rather than SolarAPP+. The City's page describes two steps: apply through the Symbium portal and pay the fees there, then log into the City's Civic Access system to submit the documents and pay the City's application fees. The document list includes a line drawing, the solar layout, equipment specifications and the Symbium approval, and the City publishes an inspection checklist alongside it.

Because both steps sit with the applicant, ask each bidder to confirm it will do both, and to show which fees are already in its price. The contract should say plainly who is responsible for the permit and the inspection.

What Pioneer changes for an Auburn solar home

Auburn, Colfax, Lincoln, Rocklin, Loomis and most of unincorporated Placer County formed Pioneer Community Energy's original service area in 2018. On a solar account, Pioneer handles the generation side. New systems since April 15, 2023 are on the Solar Billing Plan, where exports are valued at a variable export rate and positive charges are paid monthly; older systems on net energy metering earn retail credits that roll forward.

Pioneer reviews each solar account over the prior twelve months during the March or April billing cycle and pays Net Surplus Compensation at half a cent per kWh above PG&E's rate, by check if the amount is over $50 and as a bill credit otherwise.

What an Auburn quote needs to explain

A comparison to ask for

Ask two Auburn bidders for the same deliverables: the Symbium approval and the City application they will file, a roof layout showing every plane and obstruction, the monthly production estimate next to your monthly Pioneer and PG&E usage, and any battery priced as its own line. Differences in those items explain most differences in price.
